Dive Computers
Dive computers are an essential piece of equipment for modern scuba divers, transforming complex dive planning into clear, real-time information at a glance.
Worn on the wrist or integrated into a console, these compact devices continuously monitor depth, time, and ascent rate, using advanced algorithms to calculate safe limits and decompression requirements throughout your dive.
Gone are the days of relying solely on dive tables—today’s dive computers provide instant feedback underwater, helping divers make informed decisions, extend bottom time safely, and reduce the risk of decompression illness.
From entry-level models designed for simplicity and ease of use, to advanced units with multigas capability, air integration, and digital compasses, there’s a dive computer to suit every level of experience.
Many modern dive computers also feature Bluetooth connectivity, digital logbooks, and customisable settings, allowing divers to analyse their dives, track progress, and tailor their experience to their individual needs.
Whether you're exploring shallow reefs, progressing through training, or planning technical dives, a reliable dive computer is your personal dive assistant—keeping you informed, safe, and in control every time you enter the water.
Dive computers allow the user to track important dive parameters such as depth and time. Some models include "Air Integration" which also tracks cylinder pressure and in turn can tell you your remaining air time, remaining air pressure and can calculate consumption rates as well as other useful information.
Please Note- All dive computor boxes are opened, quality checked, then resealed before despatch- To check the battery condition.
This pre delivery check in no way voids your warranty. This check assures the battery has adequate battery capacity, before your use.

Sirius Dive Computer
Mares designed the new Sirius watch-style dive computer with the aim of perfectly combining technology and elegance.
The characteristics of this dive computer feature top-of-the-range technology both for recreational and Extended Range divers. The recreational diver will see a simple screen, with the possibility of reading tank data thanks to the optional tank module.
The Extended Range diver can insert up to five nitrox and trimix mixes to manage technical dives. The interchangeable strap allows the Extended Range diver to use any suit thickness. Its refined style makes the Sirius the perfect accessory, even out of the water.
Available in black or black/silver versions.
Quad Air Dive Computer
Simple to use and has an excellent autonomy. thanks to its clear display and giant data viewer, the information is instant and readable at a glance.
The user interface is divided into three segments: one for depth, one for time and decompression and one for cylinder pressure.
For an even more intuitive reading of the data, Mares has increased the communicative effectiveness of the most important parameters by displaying them in bigger numbers, while the two secondary parameters are displayed in a way that takes up less space on the monitor.
Among the Quad Air's strengths are its low battery consumption (user-replaceable with standard commercial batteries), which offers up to 150 dives, and the integration of tank data - air - for up to three transmitters which are sold separately.
The probe positioned on the first stage, as well as sending data to the Quad Air via radiofrequency features a LED that uses colour coding (green/above 180 bar, yellow/100 bar, red/50 bar) to provide quick and intuitive communication to the diver and their companions.
During a dive, the four buttons on the dial - those on the left have the same functions as those on the right - are mirrored so that it is always easy to operate the Quad Air regardless of which arm it is worn on. The 'Runaway Deco Alarm' alerts the user when staying at the current depth will result in a significant increase in mandatory decompression stops; the 'Deco Dive Planner' adapts the surface interval input to your needs.
The multi-blend function, which tunes three different probes and mixtures in a single dive without looking at the gauge, completes Quad Air's customisations.
